Presentation from PHPConf 2009
Employee +0 Vote Up -0Vote Down

October, 8 I did master-class about catching error in SQL application at PHPConf 2009. Who speaks Russian can get slides here: pdf and odp.

There were several things which were interesting for me during my talk.

First is interaction with audience of different educational (or better to say MySQL practice) level. I should make a note for feature how to solve moments when 1/3 of audience listens carefully and is just right for the talk, another 1/3 knows things I am talking at the moment already and last 1/3 needs explanations of basic things such as what is difference between table-level and row-level locks. Probably I should create list of

MySQL University: The Spider Storage Engine
Employee +1 Vote Up -0Vote Down

This Thursday (October 15th, 13:00 UTC), Giuseppe Maxia will present the Spider Storage Engine. Here's from the abstract: Everybody needs sharding. Which is not easy to maintain. Being tied to the application layer, sharding is hard to export and to interact with. The Spider storage engine, a plugin for MySQL 5.1 and later, solves the problem in a transparent way. It is an extension of partitioning. Using this engine, the user can deal transparently with multiple backends in the server layer. This means that the data is accessible from any application without code changes. This

Setting up LVM on Suse Linux
Employee +0 Vote Up -0Vote Down

You can do all sorts of magic with LVM, like backing up MySQL using file system snapshots, but in order to do so you need to set it first. When installing a new computer with Suse Linux I found that this was harder than expected, unless you know what to do. Needless to say, I didn't, but some friends gave me a hand on IRC, and now I do. :-)

So I wrote a little article about this which you can find here, in an effort to save others some time. The article is about setting up LVM with Suse Yast, but you can probably use it for other flavors of Linux, too.

How I stopped worrying and learned to love Twitter
Employee +2 Vote Up -2Vote Down

I was warned by my brother a while ago that should I start tweeting, he would stage an intervention. I had already confessed to accounts with facebook, multiply, myspace, and several others (disclaimer/explanation: all of those sites are customers of my longtime employer (http://www.mysql.com)). Twitter, to the uninitiated, looks like the crack cocaine of social networking that turns the weekend photo-poster into a hardcore jittering lifecaster. Nobody wants to see their family member come to that, right? But follow along, twitter has purpose. Or just skip to the bottom.

New role for me too...
+4 Vote Up -0Vote Down

Some weeks ago I've resigned from Sun Microsystems, where I worked as a MySQL Telecom Sales Engineer. Beginning July 13th I will take on a new role in the MySQL ecosystem, as "Project Manager and COO" for Monty Program Ab.

Since it can be argued I'm moving to a competitor, and I was working in a customer facing role, upon resigning I had to immediately return my computer, phone, etc to Sun, and my login accounts, including email, were terminated. I've gotten some comments about this (like: "Is there no trust in the world anymore?" and "How can you treat anyone like that?") and I cannot stress this enough: This is normal, I expected it, indeed brought it to my managers attention myself. If nothing else, think of it this way: This precaution also protects me from any misunderstandings and/or false accusations. Besides, starting your vacation by returning your laptop and removing your email

Leaving Sun/MySQL but not the community
+0 Vote Up -0Vote Down

I thought I would put out a quick note about this right now, I am going to be leaving Sun next week. I do have some plans which will start to materialize over the next few weeks and months so stick around for that. Even though I am leaving the company, I will still be lurking and working on all think database and performance related. This should not have any bearing on BigDBAHead.com or Waffle Grid, hopefully this will only mean I will post more and spend more time doing crazy and cool things!

I wanted to thank everyone at MySQL who I worked with and learned from over the past few years.

I have been busy lately thanks to my internship project, which almost got screwed up. I was working in a team of 4 people, where we were building a web application, that was initially deployed at JBoss Server using JBoss Eclipse IDE (old version). Also, we had to interact with the centralized Oracle Server to setup our database for running the website.

Now, having being trained on some of those technologies in past few months, I thought it won’t be much of an issue. However, at the beginning of this month, I faced some weird issues which had no obvious answers. There weren’t any silly mistakes either. We were facing some issues with Oracle connectivity. I am not blaming Oracle or the company where we did the project. But, mix of old and new technologies, turned out to be quite confusing resulting in lot of trouble.

We were running out of time, so we

Let me introduce myself
+0 Vote Up -0Vote Down

This is a first entry on my new blog. Maybe the first statement can be just “First post!!!”, but I want to tell my potential readers why this blog was founded, what’s its purpose and what you can hopefully find here in the future.

The original reason to create this blog was to have some place where I can post my ideas about my work. I’m currently working as a package maintainer in SuSE and sometimes I’m facing some things that I think people should know about. But who reads mailing lists nowadays? If I’ll be good at blogging, I’ll be googleable and therefore these idea may actually find some audience. Well, other thing is that my first goal is to get aggregated on Planet SuSE, once this site will be finished enough.

While I was thinking about this stuff, I realized that this may be a good opportunity to create some personal pages

Redefining Spam, in the age of Twitter
+0 Vote Up -1Vote Down

For the past few months, I’ve been helping my friend develop and market Philtro .
We’ve gone through various iterations of the elevator pitch for it, and the one that seems to be kinda working, is: “It’s like a spam filter for your Twitter account.”

At SXSW, I got the opportunity to talk to Guy Kawasaki about this tool, and he said “There is no spam on twitter, if you don’t like it, don’t follow them”.

Dinner with Monty and others
+0 Vote Up -0Vote Down

So we had a very nice dinner with Monty and the Finnish "MySQL Ab alumni". It was to my surprise augmented by Sergei Golubchick, whom I had never really met face to face and was delighted to be seated next to. Also a first for me was to meet Pekka Nousiainen, from the MySQL Cluster team. Which is funny because I kind of work together with him on IRC and email, but we had never met before "in real life" either.

Before the dinner I had asked in a rather cryptic message people to share some MySQL memories on a separate page on this site, followed up a couple days later by Kaj's less cryptic message. I printed whatever had arrived before I left for the restaurant and read a few snippets out loud. I should say that Monty

Site is (almost) back...
Employee +0 Vote Up -0Vote Down

Sorry for the downtime of this site - until around a week ago I hosted my home page on a trusty Genesi Pegasos II system (powered by a PowerPC G4 Processor clocked at 1GHz, using Debian 4.0 PPC with 512 MB of RAM), serving these pages from my home DSL connection. Unfortunately this system provided no means of redundancy - the hard disk drive died.

Luckily I perform frequent backups, so I moved most parts of the site to a shared hosting space now - the picture gallery is unfortunately too big to fit into the space that I have there. I'll try to move the pictures into my Flickr account instead, but this will take some time.

Note that the primary domain name of this site is now lenzg.net - lenzg.org, (the domain

Yet Another Switch Page 2.0

It’s been 4 years since I switched to the Mac. A few years ago I made a page for other switchers. I’m making a new list, as a lot of my friends have finally switched themselves, or are thinking about it. Please share and add your favorite apps in the comments.

The List
Here is the software I use, in order of importance to myself.

  • QuickSilver: If you don’t like using the mouse, this is your friend. It’s not just an app launcher, with the power of chaining, I can create tasks in RTM , straight to iCal, Calculator, and send quick emails with text snippets
  • Terminal.App: This comes with OS

    OQ and the GFC, lessons about email
    +0 Vote Up -0Vote Down
    As you may know, Open Query is entirely self-funded, which means the banks owe OQ and me money not vice versa. Things like interest rates are of little concern, which is helpful in volatile times! Of course I do rely on my bank staying in business, but that's now subject to a government guarantee in Australia so I'll just have to go with that for now ;-)

    So far, OQ has not experienced much from the economic troubles. But I'll tell you about the possible encounters, since I think they're of interest and lessons can be learnt.

    We give away one book to each student at a training day, that is, provided they've paid on time (basically a personalised quick payment bonus). I've got a small shortlist of decent books, but generally I've been handing out copies of

    A Long, Strange Road Trip

    « Post 3 | This is the 4th post in my MoFo Futures 2009 blog series

    “When I was a child, my mother lectured me on the evils of ‘gossip.’ She held a feather pillow and said, ‘If I tear this open, the feathers will fly to the four winds, and I could never get them back in the pillow. That’s how it is when you spread mean things about people.’ For me, that pillow is a metaphor for Wikipedia.” — John Seigenthaler Sr.

    So the future pulled up in her shiny big metaphor and we got in. In the beginning, our road trip made sense, all well-ordered highways and wholesome roadside attractions. Somewhere along the way, we hit bat

    Christmas party at the Widenius residence

    Last Friday I got to enjoy the benefit of being a MySQL'r and located in Finland: We were invited to Monty, Anna and Maria for a MySQL Christmas party. Now that we are part of Sun, the company of course organises its own official Christmas party (who organises parties on a Thursday???) like all companies do, but a special MySQL party was still a very good idea, thanks Monty for inviting us. I especially enjoyed meeting some of the MySQL'rs who had recently either left Sun or happened to be on maternity leave.
